Math: Area of a Triangle

Semiperimeters.  I have no recollection of ever learning this before, but I learned that it can be useful if you need the area of a triangle and don't have the height.  Proud that I'm still keeping up with K's math, even if just barely.

Oh, and the easier way to calculate area, 1/2bh, we remember as a double.  That's one half of a baseball homerun (b, h).  It works!
